CUPS Error

I had no problem installing my Samsung ML2250 printer with Sarge.
However, now I can't get it to work after I upgraded to etch. The
installation script successfully completes, but when I try to add the
printer, I get the following error:

"CUPS_BackEnd: get-printers failed: client-error-not-found".
What does this mean? Thanks for any help you can provide.
